I-BET 151 is part of a novel series of quinoline isoxazole BET family bromodomain inhibitors, a family of four proteins that selectively bind to aceylated lysine residues in histone. I-BET 151 play key roles in many cellular processes, including anti-inflammatory gene expression, mitosis, and viral/host interaction by controlling the conformation of histone acetylation -dependent chromatin complexes. Studies have shown that I-BET 151 increased ApoA1 expression within the nanomolar range in human hepatic cell line HepG2. The upregulation by I-BET 151 suggested potential anti-inflammatory activities upon administration.
